Title: | Hinged bis-porphyrin scaffolds I: The synthesis of a new porphyrin diene and its role in constructing hinged porphyrin dyads and cavity systems | Contributor(s): | Tang, Hesheng (author); Dong, Zemin (author); Merican, Zul (author); Margetic, Davor (author); Marinic, Zaljko (author); Gunter, Maxwell J (author); Officer, David (author); Butler, Douglas (author); Warrener, Ronald (author) | Publication Date: | 2009 | DOI: | 10.1016/j.tetlet.2008.11.109 | Handle Link: | https://hdl.handle.net/1959.11/7817 | Abstract: | Norbornene building BLOCKs formed by the reaction of porphyrin 1,3-dienes with norbornadiene or dimethyl tricyclo[4.2.1.02,5]nona-2,7-diene-3,4-dicarboxylate were coupled with an ester-activated cyclobutene epoxide BLOCK to afford the first examples of hinged porphyrin-spacer-acceptor dyads. Similar dual coupling with a bis-(cyclobutene epoxide) formed doubly hinged POR-spacer-POR scaffolds separated by up to 16σ-bonds. The ability of the doubly hinged ZnPOR-16σ-ZnPOR scaffold to adopt cavity-shaped conformations was indicated by semiempirical AM1 calculations of these conformationally flexible bis-porphyrin scaffolds. | Publication Type: | Journal Article | Source of Publication: | Tetrahedron Letters, 50(6), p. 667-670 | Publisher: | Elsevier Ltd | Place of Publication: | United Kingdom | ISSN: | 1873-3581 0040-4039 |
